Apart from his books, his achievement is his house which is like a banquet set against rich dark wood, plush wallpaper, Gobelin tapestries and recycled furniture. An old door is a table, a chair back serves as a lintel, cotton reels double as candle-holders in a chandelier. And in a clear sign of his enormous self-regard, the writer even signed his initials in Delft tiles. I admired his massive billiard table, red room decorated with chinoiserie, the guest bed where Alexandre Dumas slept and his shrine to his ancestors - he dabbled in spiritualism.
